Shipping huggingface_hub every week with AI, open tools, and a human in the loop

Releasing the core `huggingface_hub` library has been accelerated from a multi-week manual chore to a rapid weekly cycle through an automated pipeline. This system uses GitHub Actions and an open-weights AI model to instantly draft release notes, turning hours of tedious work into a quick review task. A human developer always remains in the loop to approve the AI's output, ensuring the final notes are accurate and well-written. To prevent errors, the workflow automatically verifies the AI's draft against a ground-truth list of all included changes, guaranteeing no pull requests are missed or invented.
